According to NCCI, CPT 97140 and 98940 can be performed on the same area when delivered during "separate encounters" with the same patient. Two definitions have been provided: 1) Different providers perform the two procedures on the same date of service. For example, if a PT performed the adjunctive physiotherapy procedure and a chiropractor performed the adjustment, it would qualify as a separate patient encounter. This rule includes ONLY licensed providers, such as chiropractors, physical therapists and does not include chiropractic assistants; 2) The same provider performed the two procedures during a second visit on the same date of service. In this case the patient would receive his or her chiropractic adjustment during a visit in the morning, and physical therapy at a second encounter later in the day.
When billing, you must add modifier 59 (distinct procedural service) to CPT 97140 if it was performed on the same day as CPT 98940. Documentation must also support that the procedures were made during separate encounters. Failure to append the modifier 59 AND provide documentation might result to payment denial.
